Sadly I could not find a way to take a photo that shows just how glorious these dice look in actual use. (I'm not exactly a professional photographer.) These are a set of gaming dice cut from dichroic prisms. This makes them sparkle in unusual ways and colours that makes them unique of all the dice I own. They're instant eye-grabbers on the table.
I bought them off of Taobao (like โฆ pretty much everything I've bought in the past decade or so ๐). You can probably find them on AliExpress as well, I would guess.
